"C'T also claim to have spoken to a number of developers behind the scences at Gamescom, who they say have confirmed anonymously that the 3D performance of the PS4 is indeed better than that of the Xbox One."

They went around to confirm what AMD spokesman said was true, meaning AMD did state those for fact.

I'd expect the 3d performance of the PS4 to be better.

And seeing as Cerny has detailed the hell out of the bus's and modifications..

really guys.

Sorry but you was the guy that said Xbox One had hUMA and PS4 didn't
When in actuality it's impossible for the X1 to have it due to its Ram.setup but possible for PS4 to have it.
And to Answer the question you asked pages back, I'm sure Cerny said the GPU has direct line to the Ram in one of his interviews
Months ago.

Its completly possible for the xbox one to have HUMA. Nothing precludes it.

"First, we added another bus to the GPU that allows it to read directly from system memory or write directly to system memory, bypassing its own L1 and L2 caches. As a result, if the data that's being passed back and forth between CPU and GPU is small, you don't have issues with synchronization between them anymore. And by small, I just mean small in next-gen terms. We can pass almost 20 gigabytes a second down that bus. That's not very small in today’s terms -- it’s larger than the PCIe on most PCs!

As I say that particular bus is well documented. Not at all new.
By it very definition it needs to pass through the CPU caches.

"Kabini doesn't support hUMA" which is the APU that the PS4 is based on. Which make the AMD rep comments inaccurate.

"We don't provide the 'easy to program for' console that (developers) want, because 'easy to program for' means that anybody will be able to take advantage of pretty much what the hardware can do, so then the question is, what do you do for the rest of the nine-and-a-half years?"
--Kaz Hirai, CEO, Sony Computer Entertainment

UPDATE: AMD contacted me again to make another comment. Essentially, they said that the correction statement to the original statement claiming hUMA was part PS4 was "inaccurrate" but that this correction does NOT mean the opposite claim is true. Even when pressed for a more specific and debate-ending comment, AMD wouldn't give us any more information. So does the PS4 have support for some type of heterogeneous unified memory? Maybe. And the Xbox One? Maybe. At this point, I'd stop listening to anything AMD has to say on the subject as they are likely to recant it shortly thereafter. Many readers have emailed me with their thoughts and I personally feel that its more likely the original statement from AMD (that the PS4 will have the edge with a hUMA design) will turn out to be the truth in the long run...

That's not exactly how it works. These are heavily modified pieces of hardware. You can't look at what the hardware parts were based on and say that it does or doesn't support hUMA going off that. If they just threw a Kabini APU in there, then sure, it wouldn't support hUMA. It was stated loud and clearly by AMD many times though that they leveraged the building blocks of their full 2013 roadmap.

I've been assuming for awhile that the PS4 may be going their own route to achieve hUMA that differs from the official physical method AMD will implement it in their upcoming hUMA APUs, but that it'll have the same basic end result. Here's some stuff possibly backing that.

The big kick I have been getting out of this entire thread/incident is that everyone is pinning their hopes on this one tiny function of the machine. It is a brilliant piece of technology but it's nothing astoundingly amazing at the same time. It's just feels like every other console war we've had before.

Finding the single differentiator and then using that as a point of argument of side A vs side B.

It supports HSA, it supports a form of sharing data from CPU->GPU.
They both do. That's nothing new.
Its not quite the same as sharing memory pointers which is what HuMA allows you to do.

You all should just be happy that it supports a form of data sharing.

edit ~ Damn you Larry! Got to it before me, ya bastard.

As I said, and have been saying for a while..it's not HuMA, but its a work around to give you a similar result.

True or not it just feels so pointless this time around.

This is not the single differentiator between side A and Side B.

Architecture maybe very similar but you have a huge difference in Ram and GPU components. PS4 having huma will not change which has better spec.

Yeah....sounds like AMD revealed too much and somebody didn't like it.

There is a lot at stake when something like that is said. You pretty much have to be hush hush about this stuff when you are catering to multiple platforms, which is why I was so surprised that AMD mentioned it.

On one hand you have AMD who wants to tout their new tech as the future to gain an advantage in their market, but on the other hand, they have a customer who is not using that tech.
